Hi. I've just bought 4 of these motors for my quad build. I will use it with 10x4.5 SF props, 30A Plush ESC and 3s battery. How large lipo capacity should I buy? I'm thinking of Zippy Lipo 3s 4000mAh 45C (55C burst). Is this lipo too big?

It depends. I recommend to start with medium. It won't damage your motors and if you feel it too weak you can use the high timimg. The higher you go the lower your battery life will be but with plush escs it is hard to see a difference between the differents timings. You are the only one who can judge the best timing !

Tested this motor with a 10x4.7 slow fly prop, 30 amp esc and 3s 20c lipo battery. I was quite skeptical about this motor due to the bargin price. Anyway, here are my results:
180 watts and 18 amps
The motor gets warm at full throttle. Yet, I never need to use full throttle. This motor is powerful. It is also a smooth and quiet. My other motors aren't as smooth. My slow stick flies with a viciousness now. It gets up high in no time. The motor comes in a plastic case with a prop adapter, mount and information. The cost is under $8, yet it feels like a quality built motor which includes information. I curious to see the lifespan of this motor. Be certain to solder the bullet connectors on well or the motor will stutter like mine did. I had to re-solder the connectors again and it worked. I really like this motor!!

I have 3 of these total... two in a Multiplex TwinStar and one as a backup. They're fantastic motors for the price. I run 8x6 APC electric props on them (not the SloFly models, the standard electric props) and they always come down cool. 9x6 prop stressed them a bit. 8x6 was the sweet spot. Efficiency is awesome on these, too. I can fly for about 15 to 20 minutes and only use 1100mAh on my 2200mAh packs. Great stuff!
